Use the sum rule and the derivatives of #sqrtt# and #sect#.

Explanation:

The derivative os a sum is the sum of the derivatives, so we differentiate term by term.

The first term #sqrtt# has derivative #1/(2sqrtt)# (Use the power rule)

The second term #sect# has derivative #sect tant#

So #g'(t) = 1/(2sqrtt) +sect tant#
